Super-polished fused silica and fused quartz wafers

Super Polished Fused Silica and Fused Quartz

Wafers, substrates and optical windows now can be super-polished to have a 3 - 4
Angstrom Ra surface finish.

The surface finish of a polished fused silica wafer can be improved by repolishing
to reach 3 - 4 Angstrom Ra superpolished smoothness. If the polished surfaces have
been compromised during processing, these surfaces also can be improved by repolishing
to 3 - 4 Angstrom level with minimal stock removal.
